WI-IIFFLETREE.

Specification of Letters Patent.

Application filed May 5, 1913.

Patented Jan. 6, 1914.

Serial No. 765,629.

To all whom it may concern Be it known that I, HERMAN RAsMUssEN, acitizen of the United States, residing at Sedgwick, in the county ofHyde and State of South Dakota, have invented certain new and usefulImprovements in VVhitlletrees, of which the following is aspecification, reference being had to the accompanying drawmgs.

This invention relates to new and useful improvements in whitlletreesand more particularly to a whiffletree Which is constructed of sheetmetal or other similar material, the object of the invention being toprovide a whiftletree of the above character in which the pull upon thesame will be equally dis tributed and not throw the strain upon anyparticular part thereof.

Another object of the invention is to provide a whifiletree of the abovecharacter which will possess advantages in points of efliciency anddurability, is inexpensive of manufacture and at the same time is simplein construction and operation.

lVith the above and other objects in view, this invention consists inthe novel features of construction and the combination and arrangementof parts to be hereinafter more fully described, pointed out in theclaims and shown in the accompanying drawings, in which Figure 1 is alongitudinal sectional view of a whiflletree constructed in accordancewith my invention; Fig. 2 is a top plan view; and Fig. 3 is a transversesectional view.

Referring more particularly to the drawings, 1 indicates the body of thewhitfletree which is preferably constructed of sheet metal or othersimilar material and is substantially rectangular in cross section.Arranged at each end of the body are suitable blocks 2 provided withopenings through which are adapted to pass the bolts 3, said boltspassing through the side walls of the body 1 and secured in position bymeans of the nuts 4 which are threaded upon one end thereof. The blocks2 are provided with a central bore 5 in which is arranged one end of theconnecting rods 6, said rods being secured to the bolts 3. The innerends of the rods are connected to the outwardly projecting ears 7, saidears being integrally formed with the substantially rectangular plate 8which is arranged within the movable block 9.

The block 9 may be constructed of wood or other similar material andprovided with a plate 8 having the ears 7 thereon or this block may beformed of metal and having the ears 7 formed upon its longitudinal edgesadjacent the inner end thereof. In constructing the block of wood, Iprovide the cross pins 10 which extend through the block to securelyhold the plate 8 in position. The

outer end of the block 9 is provided with the suitable transverseopening 11 adapted to receive the bolt of a clevis or other devicewhereby the whifl'letree may be readily secured to a plow or any otherimplement or a vehicle.

Secured to the ends of the body 1 are the trace hooks 12, the ends ofwhich are mounted for pivotal movement upon the ends of the bolts 3 sothat the intermediate portions of the hooks may be disposed in anysuitable position.

From the above, it will be apparent that I have provided a simple anddurable whittletree whereby the strain or pulling power is equallydistributed throughout the same. It will also be apparent that the bodyof the whiffletree may be constructed tubular in cross section andprovided with a longitudinal groove, through which will project theplate 8, limiting the use of the block 9. It will be obvious that myimproved whiffie tree is extremely simple in construction and can bemanufactured at a comparatively low cost.

l/Vhile I have shown and described the preferred form of my invention,it will be obvious that various changes in the details of constructionand in the proportions may be resorted to for successfully carrying myinvention into practice without sacrificing any of the novel features ordeparting from the scope of the appended claims.

What I claim is 1. A whiffletree including an elongated bodysubstantially rectangular in cross section, a block arranged in each endof said body, a transverse bolt extending through the block and thebody, a movable block centrally arranged within the body, and means forconnecting said block with the bolts.

2. A whiffletree including an elongated body, a block arranged in eachend of the body, bolts extending through said blocks and the ends of thebody, a movable element centrally arranged within the body, and contion,a block arranged in each end of said body, bolts passing through saidblocks and the ends of the body, a plate arranged Within said body, earsformed upon said plate at the inner end thereof, and connecting rodshaving one of their ends connected to said 10 ears andtheir other endsconnected with the bolts at the ends of the body.

In testimony whereof I hereunto affix my signature in the presence oftWo Witnesses.
